Abstract
The work on feeding and biotic potential of coccinellid predators on coriander aphid was studied under ambient laboratory condition at the Department of Entomology, SKN College of Agriculture (SKNAU), Jobner and observed that the first, second, third and fourth instar grubs of Coccinella septempunctata were consume 33.60, 55.22, 129.11 and 193.88 aphids during their respective stages. A grub of C. septempunctata consumed 411.13±10.82 aphids during its total life span. The adult male and female beetles consumed 1425.50±231.82 and 1983.25±177.92 aphids during their adult longevity with daily aphid consumption ability of 54.35±2.95 and 64.14±3.90 aphids per day, respectively.
